DIGESTION VI SI RLE TO THE EYE. 
381 
part of July, the horse was cast, and, having had a small seton nee- 
dle made for the purpose, I began by carefully probing the wound, 
and found that the sinuses extended in several directions ; and 1 
was obliged, in order to afford depending outlets, to insert three 
setons through the foot, one to the inside heel to the seat of corn 
from the entrance of the wound, another from this part to the 
commissure between the bar and frog, and the third from the heel 
to the centre of the frog. The setons, of course, were regularly 
moved and dressed ; and when healthy matter appeared they 
were diminished, and the solution of zinc injected. In less 
than a month the setons were removed, and the coronet blis- 
tered; and during this time the hind leg had been again blistered. 
The horse now becoming free from lameness in both legs, was 
soon afterwards put to work, where he has continued for the 
last four months and upwards, never doing less than one hun- 
dred miles per week in a four-wheeled phaeton. The result 
was the more pleasing and satisfactory, as during the time the 
setons were in the foot the owner was advised by a friend to have 
the horse shot. 
This case being in some respects novel, I send it for insertion 
in The Veterinarian. The short period between the inser- 
tion of the setons and the healing of the ulcers deserves remark, 
and prompts me to suggest the propriety of inserting setons in 
many cases of deep-seated quittors, with a needle purposely pre- 
pared for the sinuses. 
THE PROCESS OF DIGESTION VISIBLE TO 
THE EYE. 
By Dr. Beaumont. 
[We account this one of the most valuable contributions to 
physiology of which modern times can boast. What will be- 
come of many of the pretty theories of the process of digestion, 
we presume not at present to determine.] 
** It is rarely, indeed, that we can actually see what is going 
on in a healthy stomach ; but in a few instances this advantage 
has been enjoyed, and turned to account in investigating the 
phenomena of digestion. By far the most instructive example 
of this kind, which has ever occurred, has lately come under the 
observation of Dr. Beaumont, of the American army ; and, as 
that gentleman eagerly embraced the opportunity so unexpect- 
edly afforded him of testing the prevailing doctrines by a series
